This is a very easy fix for sound in flash with KDE 3.4 and firefox 1.5 and may also work for 1.0.8 .

Simple edit the icon and add -artsd to the command line. Start firefox and visit a flash site/game/what ever where you want sound. Should work immediately although you may also have to restart kde to get it fully operational.

Err, what icon? My firefox is 1.0.8, Kde is 3.4.3. I don't see any sort of icon that links to flash, neither in Firefox nor Kde. The video part works fine for me, but sound obviously doesn't.
Maybe you can provide the command string associated with this icon so I can maybe manually run flash with that option? Thx in advance!

I have some parts of KDE 3.4 but my main WM is Fluxbox. I have also Firefox, but I use also Opera. I wrote that I use plain ALSA, because I don't use Arts for my KDE apps. So why I couldn't to ask in that topic?_________________SasQ

firefox -artsd doesn't change a thing for me. Having to boot windows to show ppl a flash movie cause my linux can't handle it is quite embarassing btw :>
I'm running arts, I do have sound all over in linux/kde, I don't have sound muted for flash, nor is the volume set to 0. Any ideas guys and girls?
